Battery system

摘要

A battery system having a battery, an overcurrent switch-off device in which a first current range with a maximum switchable current, and a second switch-off current range having a minimum switchable current. The maximum switchable current of the first current range and the minimum switchable current of the second current range lie above a maximum current of an operating current range, and the switchable current of the second switch-off current range is at least predominantly greater than the switchable current of the first switch-off current range.

1. A battery system, comprising:
a battery having lithium-ion cells; an overcurrent switch-off device with at least one switching relay having a first switch-off current range with a maximum switchable current; at least one fuse connected in series to the at least one switching relay, the at least one fuse having a second switch-off current range with a minimum switchable current, the switchable current of the second switch-off current range being greater than the switchable current of the first switch-off current range, the first switch-off current range and the second switch-off current range having an overlapping range; and a first current sensor to detect current from the battery, wherein:
the maximum switchable current of the first current range and the minimum switchable current of the second current range are greater than a maximum current of an operating current range,the first current sensor is configured to detect current at least up to the minimum switchable current of the second switch-off.
